| Neural oscillatory activity is an emerging property of the brain. The patterns of brain oscillations depend on its functional state and serve different tasks. Sleep slow rhythms can mediate the processes of synaptic plasticity and contribute to memory formation. Fast oscillatory activities are associated with cognitive processes and are involved in transmission of information through the sensory pathways. Oscillations in different brain systems can be mediated by similar mechanisms therefore providing common ground for studying brain functions. Drawing on results obtained with biophysical network models of the thalamocortical system, I will discuss intrinsic and synaptic factors contributing to long-range synchronization properties of rhythmic brain oscillations. |
